Warning can't determine annotations of missing type $Proxy89

[lekkie_lomotayo]

I am trying to write create an aspect in my camel application with the following snippets:

<ctx:component-scan base-package="com.interswitchng.techquest.paydirect.payment.notification.service.soap" />

     <ctx:annotation-config />

     <aop:aspectj-autoproxy/>

     <aop:config>

          <aop:aspect ref="systemAspectAdviceApi">

               <aop:pointcut id="transactionProcessorPointCut" expression="execution(@com.system.service.util.annotations.MonitorRequest * *(..))"/>

               <aop:before pointcut-ref="transactionProcessorPointCut" method="publishTransactionCount"/>

               <aop:pointcut id="transactionExceptionPointCut" expression="@within(com.system.service.util.annotations.MonitorTransactionException)"/>               

               <aop:after-throwing pointcut-ref="transactionExceptionPointCut" method="publishExceptionCount"/>

               <aop:around pointcut-ref="transactionProcessorPointCut" method="publishTransactionLatency"/>

          </aop:aspect>

     </aop:config>

but I get the following excpetion:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'osgiDestinationRegistry': Post-processing of the FactoryBean's object failed; nested exception is org.aspectj.weaver.reflect.ReflectionWorld$ReflectionWorldException: warning can't determine annotations of missing type $Proxy100

Do you use any osgi services (eg a bean referenced from the osgi service registry). As they would return a proxy for the bean.

And since the spring framework fails with a proxy. It may indicate that.

[lekkie_lomotayo]

Yes I did. I imported OSGi services from the registry.

My AOP advice was imported as an OSGi service from the registry.

<osgi:reference id="systemAspectAdviceApi" interface="com.system.service.util.api.SystemAspectAdviceApi"/>

<aop:config>

          <aop:aspect ref="systemAspectAdviceApi">

               <aop:pointcut id="transactionProcessorPointCut" expression="execution(@com.system.service.util.annotations.MonitorRequest * *(..))"/>

               <aop:before pointcut-ref="transactionProcessorPointCut" method="publishTransactionCount"/>

               <aop:pointcut id="transactionExceptionPointCut" expression="@within(com.system.service.util.annotations.MonitorTransactionException)"/>               

               <aop:after-throwing pointcut-ref="transactionExceptionPointCut" method="publishExceptionCount"/>

               <aop:around pointcut-ref="transactionProcessorPointCut" method="publishTransactionLatency"/>

          </aop:aspect>

     </aop:config>

Are there any work around this?

[davsclaus]

I am not sure about a workaround. There may be a newer release of the projects that has a fix (eg spring / spring-aop etc.)

And I would try googling about this issue osgi / aop as it would be a common issue.
